DIAGNOSTIC TESTING FOR CAMPYLOBACTER JEJUNI OR CAMPYLOBACTER COLI INFECTIONS USING NOVEL ANTIGENS

摘要

Antigenic compositions useful in diagnostic testing for the presence of Campylobacter jejuni or Campylobacter coli comprising a PEB1 antigen obtained from Campylobacter jejuni having an apparent molecular weight of about 28 kDa as measured by SDS-PAGE under reducing conditions, a molecular weight of 28.9 +/-1.0 kDa as measured by gel filtration chromatography under native conditions and an isoelectric point of 8.5 or a PEB3 antigen obtained from Campylobacter jejuni having an apparent molecular weight of about 30 kDa as measured by SDS-PAGE under reducing conditions and an isoelectric point of greater than 9.3 or a combination thereof.
